Explanation:
There is an inverse relationship between distance and light intensity - as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, light energy becomes spread over a wider area.
The word that completes the sentence is "inverse."
The complete sentence is: "Light intensity decreases as the distance between the light source and the plant increases. This is called inverse proportionality."

Plants produce glucose by photosynthesis during the day and use cellular respiration at night.
During photosynthesis, plants use energy from sunlight to split water molecules into oxygen and hydrogen ions. The oxygen is released into the atmosphere while the hydrogen ions are used to power the production of ATP and NADPH, which are needed for the next step in photosynthesis.
This next step, called the light-independent reactions, uses the ATP and NADPH to convert carbon dioxide into glucose and other sugars. At night, when there is no sunlight, plants cannot perform photosynthesis and instead rely on cellular respiration to produce energy.
During this process, glucose is broken down to release energy for the plant to use. However, since there is no photosynthesis occurring at night, plants must rely on stored glucose to fuel their cellular respiration.

Which correctly lists the three types of rock particles that make up soil?
The three types of rock particles that make up soil are sand, silt, and clay.
Sand particles are the largest, with a diameter of 0.05 to 2 millimeters.
Silt particles are intermediate in size, with a diameter of 0.002 to 0.05 millimeters.
Clay particles are the smallest, with a diameter of less than 0.002 millimeters.
The relative proportions of these three types of particles in soil determine its texture. Soils with a high sand content are coarse-textured, while soils with a high clay content are fine-textured. Soils with a balanced mix of sand, silt, and clay are loam soils, which are considered to be the most fertile.
Soil particles are constantly being weathered and eroded, and new particles are being formed. This process of weathering and erosion is what creates soil. Soil is essential for life on Earth, as it provides plants with the nutrients they need to grow.
The theory of endosymbiosis proposes that eukaryotes descended from a primitive combination of both archaea and bacteria. What evidence supports this theory?
Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria
The reason for the clear zone may be that there is Insufficient lipolytic activity.
Why the clear zone?The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.
Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media.

2. Why does the author tout traditional use of the "one pesticide" as a first line approac
as dishonest, irresponsible, and dangerous?
The author criticizes the traditional use of "one pesticide" as a first-line approach because it is deemed dishonest, irresponsible, and dangerous.
This perspective is likely based on several reasons.
Firstly, relying solely on a single pesticide can lead to the development of pesticide resistance in target pests.
Over time, pests can evolve and adapt to the pesticide, rendering it ineffective.
By promoting the use of only one pesticide, the author suggests that it neglects the potential for pests to develop resistance, thus exacerbating the problem in the long run.
Secondly, it can be considered irresponsible because it disregards the potential negative impacts on the environment and non-target organisms. Pesticides, when used indiscriminately, can harm beneficial insects, birds, and other wildlife, disrupting ecosystems and biodiversity.
Lastly, relying on a single pesticide can be dangerous because it creates a narrow approach to pest management.
If the targeted pests develop resistance or the pesticide proves ineffective, there are no alternative methods in place to address the problem effectively.
This lack of diversity in pest control strategies leaves farmers and agricultural systems vulnerable to potential crop failures or pest outbreaks.
Overall, the author highlights the drawbacks of relying solely on a single pesticide, emphasizing the importance of adopting more comprehensive and sustainable pest management practices that consider long-term efficacy, environmental impact, and the resilience of agricultural systems.

Cholesterol is a fatty substance that's mostly made by the body in the liver.
It's carried in the blood as:
low-density lipoprotein (LDL)
high-density lipoprotein (HDL)
Eating too much saturated fats in your diet can raise "bad" LDL cholesterol in your blood, which can increase the risk of heart disease and stroke.
"Good" HDL cholesterol has a positive effect by taking cholesterol from parts of the body where there's too much of it to the liver, where it's disposed of.
You must have seen stored rice is attacked by Weevil. How can you get rid of this pest? List down 3 such pests that attack stored grains and the methods to remove them.
Answer:
Yes, Weevils are a common pest that can infest stored rice and other grains. To get rid of Weevils, you can follow these methods:
Freezing: Freezing can kill any eggs, larvae, or adult weevils present in the rice. Place the rice in an airtight container and keep it in the freezer for at least four days.
Heat treatment: You can also heat the rice to kill any pests. Spread the rice in a thin layer on a baking sheet and bake it at 150°F for 30 minutes. This will kill any eggs or larvae present in the rice.
Bay leaves: Place a few bay leaves in the container with the rice. The strong smell of bay leaves is believed to repel weevils and prevent infestation.
Apart from Weevils, other common pests that can infest stored grains include:
Indian Meal Moth: They can be eliminated by discarding infested grains, cleaning the storage area, and using pheromone traps to capture the adult moths.
Grain Mites: Grain mites can be eliminated by reducing humidity levels in the storage area, discarding infested grains, and using diatomaceous earth or boric acid to kill the mites.
Rice and Maize Weevils: They can be controlled by cleaning the storage area, using pheromone traps to capture the adult weevils, and fumigating the storage area with insecticides.
Explanation:
The exchange of gases in plants takes place through tiny pores in the leaves called __________
Answer:
stomata. Stomata are small openings on the surface of the leaves that allow for gas exchange between the plant and its environment. They are surrounded by specialized cells called guard cells, which regulate their opening and closing. During photosynthesis, the stomata open to allow for the uptake of carbon dioxide from the atmosphere and the release of oxygen as a waste product. At the same time, water vapor is also released through the stomata in a process known as transpiration. The exchange of gases through stomata is crucial for the survival of plants, as it allows them to produce the energy they need to grow and carry out their metabolic processes.

is seeda living thing explain
Seeds are not considered living things in the strictest sense of the term, but they are alive in a dormant state.
A seed is a structure produced by plants that contains an embryo, along with stored nutrients and a protective coat. The embryo is a living organism that has the potential to develop into a mature plant under the right conditions.
However, when a seed is dormant, it is in a state of suspended animation, and all of its metabolic processes are slowed down. It is not actively growing or reproducing, and it can survive in this state for a long time, even under adverse conditions.
Once a seed is exposed to the right combination of moisture, temperature, and light, it can germinate and begin to grow. At that point, it is considered a living organism, because it is actively metabolizing and carrying out the functions of life, such as respiration, photosynthesis, and growth.
So, while seeds are not living things in the strictest sense of the term, they are alive in a dormant state and have the potential to become living organisms under the right conditions.
This passage is adapted from Allie Wilkinson, “Panda Guts Not Suited to Digesting Bamboo.” ©2015 by Macmillan Publishers Limited.
Scientists suggest that the gut bacteria of giant pandas (Ailuropoda melanoleuca) may not have not evolved to efficiently break down cellulose, a hard-to-digest fiber found in the plant walls of bamboo, as previously thought.
Ancient giant pandas, which were originally omnivorous, began introducing bamboo into their diet at least 7 million years ago, and eventually switched to eating bamboo exclusively 2.4 million to 2 million years ago. The bears evolved strong jaws and a “pseudothumb” to help them to consume the plant. But unlike other herbivores, they did not develop an elongated digestive tract or enzymes to help break down tough plant parts.
Scientists studying the panda gut biome discovered that it is more closely related to that of carnivores, than other herbivores. The scientists found little diversity in the microbes that live in panda guts, and none of the cellulose-degrading bacteria typically seen in other herbivores.
Other scientists argue that some of the microbes in the panda gut might still be highly efficient at breaking down cellulose. They have pointed out that this study only examined microbial composition and not function—and microbes can change function rapidly, making it hard to predict how they perform solely on the basis of the genera of bacteria present.
Question
Which of the following tables accurately reflects the change in pandas’ main energy source over the past seven million years as ancient pandas evolved into modern pandas?
Based on the passage, the table that accurately reflects the change in pandas' main energy source over the past seven million years is 3rd table.
What is the table based on?This table is based on the fact that ancient pandas were omnivores, meaning they ate both plants and animals. However, modern pandas are herbivores, meaning they only eat plants. This change in diet is likely due to the fact that bamboo became more abundant in the pandas' environment over time.
Bamboo is a low-calorie food, so pandas need to eat a lot of it in order to survive. This is why modern pandas spend most of their day eating bamboo.

Explain how this experiment showed that genetic drift was not a cause of the antibiotic resistance
By demonstrating a consistent pattern of antibiotic resistance increase rather than random fluctuations, the experiment provided evidence against genetic drift as a significant cause of antibiotic resistance in the studied bacterial population.
To explain how an experiment showed that genetic drift was not a cause of antibiotic resistance, let's consider the following scenario:
In the experiment, a population of bacteria with varying levels of antibiotic resistance was divided into two separate groups: Group A and Group B. Each group was kept in separate environments and exposed to the same antibiotic over a period of time.
If genetic drift were a significant factor in the development of antibiotic resistance, we would expect to observe random fluctuations in resistance levels within each group over time, leading to divergent resistance patterns between the two groups.
However, the experiment showed that both Group A and Group B displayed a consistent increase in antibiotic resistance over time. This implies that there was a selective pressure favoring the bacteria with higher resistance, indicating that natural selection, rather than genetic drift, was driving the increase in resistance.

Describe the 3 lines of defense in the immune system, making sure to include if they're specific or non specific. Then identify how your body remembers pathogens and is able to gain immunity to them, as well as what is unique about the cells that do this.
Answer:
The immune system has three lines of defense: 1) non-specific physical and chemical barriers, 2) non-specific immune responses, and 3) specific immune responses. The third line of defense involves highly specialized cells called lymphocytes, including B cells and T cells, which produce antibodies and directly attack infected cells. The body remembers pathogens through a process called immunological memory, maintained by memory cells that persist in the body and can quickly produce a specific immune response upon subsequent exposures to the same pathogen. Memory cells have a longer lifespan than other B and T cells, allowing for long-lasting immunity and the basis for many vaccines.
